IMPROVEMENT IN LAVING TILES.

Speeication forming part of Letters Patent No. 120,850, dated November 14, 1871.

To all lwhom t may concern:

Beit known that I, MANLY A. BURNHAM, of the city of New York, in the county and State of New York, have invented a new and useful Improvement in Laying Tile; and I do hereby de- Y clare that the following is a full, clear, and eX- act description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanyin g drawing forming a part of this specification, in which- This invention relates to a new and useful improvement in laying tile in vestibules, halls, and other apartments; and consists in the use of a continuous stone bed or iioor above the foundation and gauge-mortar,77 which prevents the tile from being affected by the shrinking, swelling, and warping of the wood foundation beneath, the arrangements of parts being as hereinafter more fully described.

In the accompanying drawing, Figure lis a top view. Fig. 2 is a vertical section taken on the line a: x.

Similar letters of reference indicate correspond ing parts. v

A represents the tile-floor, composed of squares or pieces of marble, porcelain, or any artificial composition or material, of any desired shape or color, and laid in any manner to suit the taste. This tile iiooring is supported, first, by the foundation timbers or joists B, which rest in the walls of the building. `On these timbers a dooring of boards or planks is placed, marked in the drawing C. To prevent warping I make my wood fIoorG of narrow pieces, as represented, and place them so that they may swell without crowding each other. D is the layer of gauged mortar resting upon the iioor O, upon which the tilefiioor A is usually placed. This layer of mortar (as tile-floors are ordinarily laid) is more or less disturbed by the swelling and warping of the wood iioor beneath, and, as a natural consequence, the tile becomes loosened and uneven and frequent repairs are" necessary. As a perfect remedy for these very serious evils I interpose a continuous iioor, E, composed of marble slabs or of stone (either natural or artificial) embedded in in the gauged mortar D. Upon this stone iioor I spread a layer of plaster of Paris or other suitable cement sufliciently thick to form a level surface. Upon this the tile door is laid, the tile being bedded down so that'the upper surface will present a perfectly level plane, as represented in the drawing. The tile floor supported in this manner will notbe affected by the swelling, shrinking, or warping of the wood beneath. The pieces of tile are cemented to the stone floor E, and the adhesion of the stone iioor E to the gauged mortar in which it is embedded being perfect, all

objection to the floors laid above wood supports is obviated.

By the use of my stone floor E I am enabled to lay a permanent sidewalk or tile an area out of doors as well as indoors, and when no Wood is used in the foundation, the stone iioor E being thus supported on walls built up for the purpose. I do not, therefore, coniine myself to vestibules, halls, &c., indoors, but propose to interpose my stone'iioor in doing outdoor as well as indoor Work.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The stone door E interposed between the gauged mortar77 D and the tile of a tile iiooror sidewalk, substantially as and for the purposes described.

2. The continuous stone iiooring E, in combination with wood floor O and gauged mortar D, substantially as and for the purposes described.
